SSM spring-mybatis整合

我的spring-mybatis整合使用添加book的列子

一、首先创建了实体类Book

package cn.sun.day15ssm.entity;

/**
 * Created by Administrator on 2017/10/21.
 */
public class Book {
    private Integer bookId;
    private String bookName;
    private Integer bookPrice;
    public Integer getBookId() {
        return bookId;
    }

    public void setBookId(Integer bookId) {
        this.bookId = bookId;
    }

    public String getBookName() {
        return bookName;
    }

    public void setBookName(String bookName) {
        this.bookName = bookName;
    }

    public Integer getBookPrice() {
        return bookPrice;
    }

    public void setBookPrice(Integer bookPrice) {
        this.bookPrice = bookPrice;
    }

}
封装了bookId，bookName，和bookPrice，
创建dao层
创建一个bookDAO的接口，在接口中创建一个addBook的方法

package cn.sun.day15ssm.dao;

import cn.sun.day15ssm.entity.Book;

/**
 * Created by Administrator on 2017/10/21.
 */
public interface IBookDAO {
    public int addBook(Book book);
}
创建一个IBookDAO 的xml文件，在其中实现sql语句

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<!--映射文件的根节点
  namespace
-->
<!--映射文件的根节点 namespace -->
<mapper namespace="cn.sun.day15ssm.dao.IBookDAO">
    <insert id="addBook"> insert into book(bookName,bookPrice) values(#{bookName},#{bookPrice}) </insert>
</mapper>
注意属性要与数据库和实体类的名字一样
创建book的service层中的接口

package cn.sun.day15ssm.service;

import cn.sun.day15ssm.entity.Book;

/**
 * Created by Administrator on 2017/10/21.
 */
public interface IBookService {
    public int addBook(Book book);
}
创建实现类BookServiceImpl

package cn.sun.day15ssm.service.impl;

import cn.sun.day15ssm.dao.IBookDAO;
import cn.sun.day15ssm.entity.Book;
import cn.sun.day15ssm.service.IBookService;

/**
 * Created by Administrator on 2017/10/21.
 */
public class BookServiceImpl implements IBookService {
    private IBookDAO dao;

    public int addBook(Book book) {
        return dao.addBook(book);
    }
    public IBookDAO getDao() {
        return dao;
    }

    public void setDao(IBookDAO dao) {
        this.dao = dao;
    }
}
二、然后，在resources中创建jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql:///book
jdbc.username=root
jdbc.password=123456
创建mybatis-config。xml在其中配合别名和管理小配置

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<!--核心配置文件的根节点-->
<configuration>
    <!--别名的配置-->
    <typeAliases>
        <package name="cn.sun.day15ssm.entity"></package>
    </typeAliases>
    <!--管理小配置-->
    <mappers>
        <package name="cn.sun.day15ssm.dao"></package>
    </mappers>

</configuration>
创建applicationContextday15ssm.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:jdbc.properties"></property>
    </bean>
    <!--2.Druid数据源-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="url" value="${jdbc.url}"></property>
        <property name="driverClassName" value="${jdbc.driver}"></property>
        <property name="username" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>
    <!--mybatis sqlsessionFactory配置-->
    <bean class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="configLocation" value="classpath:mybatis-config.xml"></property>
    </bean>
    <!--dao-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="cn.sun.day15ssm.dao"></property>
    </bean>
    <!--service-->
    <bean id="bookService" class="cn.sun.day15ssm.service.impl.BookServiceImpl">
        <property name="dao" ref="IBookDAO"></property>
    </bean>
    <!--平台事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--注入什么东西 事务对象的来源，一定是Connection -->
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <!--方式三，AspectJ AOP事物管理机制-->
    <!--<tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="addBook" isolation="DEFAULT" propagation="REQUIRED"/>
        </tx:attributes>
    </tx:advice>
    <aop:config>
        &lt;!&ndash;切点&ndash;&gt;
        <aop:pointcut id="mypointcut" expression="execution(* *..day15ssm.service.*.*(..))"></aop:pointcut>
        &lt;!&ndash;顾问&ndash;&gt;
        <aop:advisor advice-ref="txAdvice" pointcut-ref="mypointcut"></aop:advisor>
        &lt;!&ndash;切面&ndash;&gt;
    </aop:config>-->
</beans>
其中由于dao层中BookDAO没有实现类所以我们使用了一个org.mybatis.spring.mapper.MapperScannerConfigurer ，mybatis-spring jar中的类使用

basePackage来给dao模拟出一个实现类
三、pom文件的配置

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

                </includes>
            </resource>
        </resources>
    </build>
</project>

四、最后我创建了一个测试类来测试一下

package cn.sun.day01;

import cn.sun.day15ssm.entity.Book;
import cn.sun.day15ssm.service.IBookService;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * Created by Administrator on 2017/10/21.
 */
public class Test20171021 {
    @Test
    // 01.事务
    public void test01(){
        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContextday15ssm.xml");
        IBookService service=  (IBookService)ctx.getBean("bookService");
        Book book=new Book();
        book.setBookName("挪威的森林");
        book.setBookPrice(200);
        service.addBook(book);
    }
}执行成功，在数据库中可以查到我们刚才添加进来的内容，整合成功！
